Stretch top card lovelace UI

I would like my first card to stretch across the entire screens and all other cards to put themselves into columns underneath it. Using panel view i can get the top card but it wont display any more.

Here is a picture of what I’m trying to achieve:
An entity filter glance card along the top
Columns of entity and history graph cards

I have also tried using vertical/horizontal stacking but that doesn’t work well on all platforms.

I’ve been at it for a few hours but don’t seem to be getting anywhere so any help would be greatly appreciated.

Thanks
